There's some stuff still going on with these that I don't understand.
I took down a light string that worked and measured no continuity at the plug, so I plugged them in and they again worked, so I rechecked continuity and now I had a reading.
Maybe outdoor usage puts invisible tarnish on the metal that is penetrated by 120vac but not by ohmmeter test voltages.
I'll find out because I will be doing this test many times and getting extremely frustrated. But there is some logical pattern to these results, I just haven't found it yet.
